These cells have been shown to produce tubules in conjunction with Cellworks Angiogenesis Tested Human Umbilical Vein Endothelial Cells (ZHC-2102), using Cellworks Angiogenesis Seeding Medium and Angiogenesis Growth Medium (ZHA-1960 and ZHA-1970, respectively). They have been validated for use in the manufacture of Cellworks V2a Kits (vasculogenesis to angiogenesis).
